Date Oct. 14, 1993In order to strengthen an elongated or a two-dimensional bearing construction structure (1) against shear forces, at least one pre-stressing means (11) is mounted in a slack or pre-stressed manner on or in the structure cross-section (4) to generate a pre-stressing force directed transversely to the length or to the two-dimensional surface of the structure when this structure is shear-loaded.
